similar to: cant decode speex file

I found the details: 44100hz, 16bits, stereo I am looking at rewriting the program to record at 8Khz/16Khz/32Khz mono only should I record at 44100hz (and convert down) or record at the required hz level? ----- Original Message ----- From: <speex-dev-request@xiph.org> To: <speex-dev@xiph.org> Sent: Thursday, June 14, 2007 3:44 AM Subject: Speex-dev Digest, Vol 37, Issue 19 >

I have an audio file compressed by JSpeex that I'm trying to decompress on the iPhone. I've been trying to work from the speexdec example in an attempt to port the core logic to ObjC. I have a class that does the decode and passes the result back to another class. (currently the other class is a unit test.) My other class is writing the converted output to disk. I compare the results of my

Just an update, and a follow-up question: I'm making progress on this issue, and will likely have something working very soon, now that I understand how the jspeex transcoding classes work. Unfortunately, I will need to make a couple small changes to the jspeex source code. My question is - is anybody using jspeex for streaming speex-encoded audio? It works great for static audio, but seems

I am hoping to use Speex for a embedded project using Philips Arm processor (50 mips) 512kb flash 32kb ram. I found in the manual that decode takes about 0.5 mips so I should have enough processing power and I compiled the lib and it seems to take less then 64K so the only issue is memory usage. I have been testing the speex decode on windows looking at the stack usage and how much is malloc.

OK, that was a stupid error in the le_int prototype. It's fixed in svn now.

Hi Chris, Thanks a lot for your help. I've been able to resolve all the errors except one. I don't have ogg.h header file, so when I try to build Speexdec.exe, I get an error d:\speex\speex-1.1.5\src\speexdec.c(44) : fatal error C1083: Cannot open include file: 'ogg/ogg.h': No such file or directory I don't have this file, but as I wrote in my previous mail, an ogg_static

Dear sir, I've a problem that the .wav file couldn't play after calling "sampleenc male.wav|sampledec male_speex_15.wav".I found that the new file male_speex_15.wav is smaller than the original file in size.I implemented the test on Linux system.The original file male.wav is 96044 bytes,while the new file male_speex_15.wav is 96000 bytes.I'm eager to know the reason.Thankyou!

Hi, I've downloaded the Speex-1.1.5 code and am trying to compile the Speexdec code using Microsoft VC++ 6.0 IDE. When I try to open the speexdec.dsw workspace, I get a dialog asking to locate the ogg_static file. I simply cancel that message, and then the project is opened in the VC++ 6.0 IDE. Now, when I simply try to compile the program, I receive this 5 error messages. error1.

Please consider using 16-bit 16kHz (wideband) instead. It's a huge increase in audio quality and the bitrate is still very low, especially if you take advantage of Speex features such as VBR. 8kHz seems totally inappropriate to me for desktop streaming audio, let alone 8-bit samples. Or perhaps your recording equipment is an original Sound Blaster from 1989? (Even that could record at

Hi! I?ve just discovered Speex, and sorry if this isn?t the right place to ask this, but I found no other mailing list (some projects have a "users" and a "developers" list separately, I guess this isn?t the case with Speex. If it is, please let me know). First, how I got here: 1. I?m looking for some low-bitrate codec to reduce the size of some very long (think 4-5+ hrs of

This is a really good point, and definitely a recurring theme on this mailing list. :) I wonder, what are some better options for handling this issue, other than to keep saying "just use 8/16/32kHz"? - Extend Speex to support other sample rates (seems unlikely..?) - Integrate a resampling algorithm into libspeex - Maintain a list of recommended resampling libraries that work well

On my personal web pages hosted by my ISP I have a collection of speex files with names ending, as usual, in '.spx'. My ISP does not provide for scripting or CGI but thanks to the "Home-Brew Streaming" idea of Dr Tak Auyeng, www.drtak.org/teaches/ARC/speex/, my friends with Windows XP can listen to such a recording without the need for a prior download of the whole file and

Hi, Jean-Marc, I have another quick question, I got following message when compile speexdec.exe: Linking... libspeex.lib(sb_celp.obj) : error LNK2001: unresolved external symbol _lpc_window Release/speexdec.exe : fatal error LNK1120: 1 unresolved externals Where does this lpc_window declare?

Thanks a lot for your replies. Where can I get Ogg static libraries header, and Ogg header files. Any place where I can download. Basically I need to create a Speex library for Pocket PC 2003, that can be used from within my .NET Compact Framework application. For this I need to create a DLL file, which essentially is my Speex decoder. For this I simply need to make use of Speexdec, since this

Hi all, I'm trying to use libspeex 1.1.10 on an ARM926EJ-Sid(wb) rev 3 (v5l). I executed the speexenc and speexdec test files and they can encode and decode. But I'm getting 95% of cpu utilization on the codification and 44% on the decodification. I saw in the post: http://lists.xiph.org/pipermail/speex-dev/2005-June/003485.html that this version of speex works fine on ARM

The encoded speex file should, by convention, be given the '.spx' extension rather than '.wav', but that is not the issue. What appears to be happening is that the '.wav' extension on your named output file from speexdec is not being recognised as '.wav' and, consequently, the file is being written as 'raw' data without the wave file header. I am not sure
